ATTORNEYS Patented May 27, 1952 UNITED STATES PATENT OFFICE TILTABLESUPPORT FOR USE IN TREATING TEXTILE MATERIAL 8 Claims. I

The present invention relates to supports for use in treating fibrousmaterial such as wool, and is more particularly concerned with supportsused in dyeing machinery, of the type sometimes referred to as cheesesor baskets.

The usual apparatus of this character comprises a perforated platformwith a central standpipe, the platform being arranged to be receivedwithin a vat or kier. After insertion into the platform is piled withwool and the dye ing operation is carried out. Then the support isremoved from the kier and the wool is usually pulled off by hand. Thereis frequently considerable difficulty in getting the wool off the suportbecause of the fact that the wool fibers become matted together duringthe dyeing operation.

The principal object of the present invention is to provide apparatuswhereby the support may be easily unloaded after the dyeing operation.

With this object in view, the present invention comprises a support fortextile material having a number of hinged platform sections togetherwith looking devices, whereby the platform sections may be held rigidlyin place for the dyeing operation and may be easily released to dump thewool after dyeing.

In the accompanying drawings Fig. 1 is a plan view of a supportaccording to the present invention; Fig. 2 is a side elevation of aportion of the apparatus, Figs. 3 and 4 are detail views of the lockingdevices; Fig. 4 being a section of line 44 of Fig. 3; and Fig. 5 is adetail on line 5-5 of Fig. 1.

As shown in Figs. 1 and 2, the support comprises a frame 6, a centralhub 8 from which radiate a number of arms ID. The arms 10 support a raill2, end rails l4, suitable internal bracing members H3, and an innerrail ll.

Rising from the hub is a perforated standpipe l8 of usual form andhaving a hoisting ring l9, as will be understood by those skilled in.this art. .All of the parts are preferably made of stainless steel.

Mounted on the frame 6 are two perforated platform sections, illustratedas semi-circular tables 20. Each platform section has suitable braces 21on its underside and is provided with downwardly extending ears 24embracing suitable ears 26 extending outwardly beyond the side rails l2of the frame. Each platform section is mounted for pivotal movement onthe ears 2B and to this enda rod 28 extends through all of them and issuitably secured at its ends as indicated by the nuts 30.

Each platform section is adapted to swing from a horizontal to anapproximately vertical position and a suitable stop device is provided.This comprises two links 32 and 34, the former being connected to theunder side of the platform section and the latter being pivoted to anear 36 on the frame. The two arms are pivoted together at 38, and a stoppin 39 prevents motion of the section beyond the vertical position, asshown in Fig. 5. The folded position of the arms and the correspondinghorizontal position of the table is illustrated in phantom in Fig. 5.

The platform sections may be locked in the following manner. At theinner edge of each platform section, there is a pair of downwardlyextending cars 40 adapted to embrace one of the rails 16 when thesection is in horizontal position. The ears 40 and the rails l6 haveregistering openings to receive a locking rod 42, the end of which isbent to form a handle 44. Each locking rod is free to slide in openingsin the end rail [4 and a bracket 45. To unlock the platform the rod issimply withdrawn. When the the rod is out, the handle portion 44protrudes beyond the edge of the platform and hence it is impossible tolower it into the kier. The handle cannot be in place below the edge ofthe platform without assuring that the platform is locked. To preventaccidental dislodgement of the latch, the rod carries a locking dog aswhich is adapted to pass behind an ear 48 on the rail ll. In Fig. 1, theleft handle is in locked position and the right handle is in re-f leaseposition.

Vertical dividing plates 50 are welded on each side of the standpipe l8and between the rails IT, to prevent the wool fibers from matting and tokeep the wool separate on the two platform sections, whereby it may bereleased from either or both of them at the same time.

In operation the support is lowered into the kier or vat with theplatform sections locked. The wool or other fibrous material to betreated is piled up on both sections of the platform on opposite sidesof the dividin plates 50. The dye' liquid is then circulated in theusual manner as is Well understood by those skilled in the art. At thecompletion of the dyeing operation, the support is removed, usually byan overhead crane, and is transported so that the two platform sectionsoverlie the places where the wool is to be dumped. Preferably a truck isplaced under each platform section. The sections may then be released byreleasing the lock and pulling the rods out. The position of the hingeis preferably such that the platform sections are slightly overbalancedwhen the locks are removed so that the wool will dump automatically.However, if desired, the balance may be such that the sections will notswing unless started by the operator; it will be appreciated that only aslight starting motion is necessary since as soon as the platformsection is tipped slightly, the center of gravity of the mass of woolswings outwardly beyond the hinge line and carries the section to itslimiting position, as indicated in Fig. 5. This avoids the necessity ofpulling off the material by hand. After dumping, the platform sectionsare readily restored to horizontal position for a subsequent dyeingoperation.

Having thus described the invention, I claim:

1. A support for treatment of fibrous materials comprising a rigid framehaving side and end rails, a standpipe at the center of the frame, aradial dividing plate extending upwardly from the frame on each side ofthe standpipe, plurality of perforated platform sections supported bythe frame on opposite sides of the dividing plates, hinge means carriedby the side rails of the frame and connected with the platform sections,said hinge means being spaced outwardly from the dividing plates, and alocking device for each section.

2. A support for treatment of fibrous materials comprising a rigid framehaving side and end rails, a standpipe at the center of the frame, aradial dividing plate extending upwardly from the frame on each side ofthe standpipe, a plurality of perforated platform sections supported bythe frame on opposite sides of the dividing plates, hinge meansincluding ears carried by the side rails of the frame and by theindividual platform sections, said hinge means being spaced outwardlyfrom the dividing plates, and a locking device for each section.

3. A support for treatment of fibrous materials comprising a frame, astandpipe at the center of the frame, a plurality of perforated platformsections hinged on the frame and movable from a substantially horizontalposition to a dumping position, and a locking device for each platformsection, said locking device including a rod extending beyond theperiphery of the section when the section is unlocked in order toprevent insertion of an unlocked support into a vat. 4.
